Washer fills with water but will not pump it out at the end of the wash or rinse cycle, leaving clothes soaking wet in standing water.
A cracked or worn pump housing causes water to drip or pool directly beneath the washer during or after the drain cycle.
Because the control board senses water still in the tub (due to a failed pump), the machine refuses to advance to the spin cycle and stops mid-program.
A seized impeller or foreign object lodged in the pump body causes loud mechanical noise when the drain sequence is triggered.
Multimeter test of the pump motor windings shows open circuit (no continuity), confirming electrical failure of the pump assembly.
💡 Pro Tip: Is Your Washer Drain Pump the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Washer fills but will not drain at end of the cycle — water sits in the drum
⚠️ Small puddle of water forming directly in front of or underneath the washer
⚠️ Washer stops mid-cycle and refuses to advance to spin
⚠️ Loud humming or grinding noise during the drain phase — pump may be jammed by a small object
🔍 Diagnostic tip: Before replacing, remove the pump and inspect the impeller cavity for coins, hairpins, or lint clogs. If the impeller spins freely but the pump still leaks from the body, the housing seal is cracked — replace the pump. Test motor continuity with a multimeter: no continuity = confirmed pump motor failure.
